ADDRESSING MACHINE.

Application filed October 9, 1922.

This invention relates to improvements in machines for printing addresses, envelopes, time cards, pay roll lists, etc., the general object being to provide a simple compact and durable machine which is adapted, in successive operations, to receive individual ac dress plates, print from the same, and discharge the plates, the whole being embodied in the comparatively cheap construction, and preferably one which is adapted to be operated by hand. l

The machine is of that type wherein there is a bed and mechanism for feeding address plates one after the other along the bed, and a platen carried by an impression arm is adapted to be brought `down onto the article t-o bc printed, which is placed face downwardly over the positioned address plate. lvleans, preferably manually operable, are provided for operating the impression arm and for feeding the address plates from the supply to the impression position and discharging them from such position and providing the inl; for the impression.

it. prominent feature of the present invention is the provision of' an operating arm independentl of the impression arm, the irnpression arm causing a definite pressure of the platen against the address plate and the interposed material irrespective of the amount of force supplied to the operating arm. This is an important point in manually operable machines as it insures a uniform impression. l

Another characteristic of my yinvention is the employment of an, adjustableconnection between thel operating arm and the impression arm for finally regulating the approach of the platen to the worlt and thereby controlling the depth of the impressi-on to produce work which is light, heavy or medium, as desired.

Another feature of the present invention is the mechanism for positively feeding the plate and for controlling the plate in its various positions to prevent inadvertent displacement thereof and to accurately center it in the printing position.

l prefer to employ as a means of inlnng, a ribbon adapted to overlie the plate at the impression point and l have provided a simple arrangement vfor carrying the ribbon and for readily installing or removing it, as well asfor feeding the ribbon and for automatically reversing the feed as one Serial No. 593,215.

spool becomes full and the other empty. This mechanism is included in my invention.

My invention includes also the mechanism employed 'for duplicating, that is printing` twice in succession from the same address plate, and for indefinitely repeating impression from the same plate, as desired; it includes also a simple and readily operable mechanism for enabling .different platen surfaces to be brought into action position, as desired,

Another feature of' the invention which may be employed is the provision of mechanii-sm for receiving the discharged address plates, storing them in a drawer, removably mounted in a sub-base beneath the machine, such sub-base and storage mechanism being adapted to be associated with a complete addressing machine, whereby the latter may be mounted on the sub-base to effect the automatic storing of the used plates, or may be employed wit-hout the sub-base as desired.

h Still another' feature embodied within my invention, which may be employed if desired. is a suitable listing attachmentillustrated and described herein which may be employed to enable the printing of addresses .on a continuous strip of paper. :is for instance, whenA making up payroll lists.

Various mechanisms contributing to 'the operation of the machine and rendering the same efficient in practice are included within my invention and will be apparent from the following description of a preferred embodiment thereof, as illustrated in the accompanying drawings.

In the drawings, Fig. l is a front elevation of the machine and sub-base therefor; Fig. la is a side elevation of a plate holding drawer which may be employed which is shown in the supply magazine in Fig. l; Fig. 2 is a side elevation showing the subbase in crosssection; lFig. 3 is ay plan View of the machine positioned on the sub-base.; F ig. 4t is a. plan View of the sub-base; Fig. 5 isa cross sectional elevation taken transversely of the machine, substantially along the line 5-5 of Figs. 2 and 3; Fig. 6 is a ho 1izontal section through the base portion of the machine proper in a plane above the operating shaft; Fig. 7 is a vertical transverse section through the base portion of the machine proper; Fig. 8 is a trag-inen- 'in `a plane parallel with Fig. 9; Fig. 11 is an enlarged vertical section through the niachine; Fig. 12 is a fragmentary vertical section, showing a listing attachment which may be employed and which appears in side elevation in Fig. 9, and Fig. 13 is a secy'tional elevation `through the ratchet operating mechanism of `the listing attachment, the relation of Figs. 12 and 13 being indicated by the correspondingly numbered line on the other figure; Fig. 14: (Sheet 9) is a fragvmentary cross sectional elevation taken `through the'bed of the machine and showing -the vrelation of the 'feed roll of the listing attachment to the bedof the machine. Fig. 15 is a plan of one form `ot address plate adapted lfor use in the specific` machine shown; Fig. 16 is a detail in verticalsection of the reciprocating plate feed mechanism; Fig. 17 is `a detail villustrating the adjustment for the depth of impression, being a vertical section on the line 17-17 ot Fig. 5; Fig. 18 Lis a detail of the mechanism infor mounting either of the ribbon spools; being an` axial section. Fig. `19 is a detail illustrating 'a dating attachment being a cross section on the line 19.-19 of Fig. 8.

The 'bed of the machine is preferably a low hollow casting, adapted to stand on a suitable support and having a substantially flat top with `a central opening from back to front through which the address plates travel, much of the mechanism being mounted within the hollow7 ot' such base. More 'particularly the base casting has horizontal top portions 10 and 11 on opposite sides o't an open `space 19., approximately vertical edge walls 13 and 14 depending itroin the outer edges of the top portions and intermediately vertical `webs 15 and 16. There is an open space 17 through the side wall 14 and suitable -transverse webs 18 and 19 connect the wall 14 with the intermediate web 16. Secured to the top oit the bed and covering the most of it are two polished plates-8 and 9 which present a smooth surtace along which the paper may be slid lto and i'rom printing position.

Atthe rear of the bed `and rising troni its upper surface is a magazine in which a supply of address plates is placed for use in the machine. This magazine vmay be adapted to receive a drawer, of the type shown in :my Patent No. 1,448,197, from which a pile of address plates is discharged when the drawer is withdrawn vertically, or it may be a comparatively short casing into which a small number otaddress plates may be dropped at a time.

When the -machine is intended to receive the drawer; the magazine may he of the nesvgeev `iorin illustrated in Figs. 1, 2 and 5, where there are provided two inwardly facing vertical cliannel shaped members 20 secured to brackets 21, mounted on the bed. These brackets in .this .case carry on their inner faces stationary cam blocks 22, which are adapted to coact with retaining springs on the drawer to release the contents when the drawer .is shoved.downwardly into place.

Thel drawer itself, designated B, is shown in vertical position pin the magazine in Fig. 1, wherein the bottom of the drawer is toward the i'ront, the side walls 7)1 extend toward the rear and at the rear ot these walls are provided with 'flanges b2. The springs referred to are designated b3; and are sccured to the side walls of the. drawer. These springs have inwardly projecting ends which are 'adapted to enter through openings 'b4 in the side walls of the drawer and stand bc- :2"

neatli the address plates A in the drawer. The inturned tongues at the lower edges of the springs are bifurcated so that they may straddle the cam blocks 22, whereby these blocks act on the inner side of the springs and serve to withdraw them. The channel shaped members 20 are provided with deeper portions of less width, indicated vat 25, to receive these springs. At the upper end these channel bars may he braced by a' yoke 26. The same drawer after discharging its contents into the supply magazine may receive the `used plates which may be stacked horizontally beneath the addressing machine, as

hereinafter described. Fig. 6 shows the i* drawer in horizontal position inserted to receive such stack.

Vhen the drawer is not employed. the supply magazine may readily comprise simply two inwardly facing channels 2S, Figs. 10 and 11, these channels being flanged at vtheir lower ends and thereby secured to the hed vin place oi the brackets 21.

The address plate may be of any suitable forni. Thus it may be ot' a type illust-rated in Fig. 15 and shown more fully in iny design application No. 1109, tiled Mar. 10, 1922, and comprise a sheet vmetal member A, having tubular edge portions a; and hav ing intermediately parallel rows ot' buttons or projections al, struck `up from it and adapted to carry under-flanged embossed strips a2. This construction, however, is citedonly as an illustration, as various types of printing plates or address .holding'nienr bers may be employed. i

i/Vhen the. plates are in the supply magazine.r the bottonimostplate rests on a pair olf horizontal rails 40, which extend lengthwise of the machine within the central opening vrear and iiiteriii'ediately by a cross Vportion 11 42 of the frame and at the front by projectionsv 44- eXtending inwardly from the webs and 16. These rails provide a slideway along which the platesare fed toward the front of the machine past the printing position and' ultimately discharged. The plates are properiy positioned laterally in the magazine before they descend onto the rails by a channel shaped member 2T. secured to the back of the magazine and having inwardly inclined tongues 29 (Figs. and adapted to engage between extensions of the tubular 'end portions a of the address plate.

In the particular embodiment illustratet there are four addr-ess plates in a row on the rails 40 during active operation; that is, to say, one plate at the base of the stach. a second plate intermediate the stack and the printing position, athird plate at the printing position. and a fourth plate in front of 1 i x l '1%.- .the printing position and ready fel di..

charge when the line of the plates is moved forward one step. This number of active plates is convenient, but may be varied, if desired.

The printing position for the plates, as shown in Fig. 11, is the second position in front of the stack, where the plate is directly over and rests on the stationary horizontal frame portion 42. At this point, the plate lies beneath a transverse inking ribbon and also beneath a platen 60 provided on an impression arm 70, all to be hereinafter more fully described. A card, envelope or other material to be printed is placed on top of the ribbon and the impression arm brought down to effect the impression.

`Then the impression armrises and the plate is fed to the fourth position shown in Fig. 11, where it remains until the next operation when it is discharged into a receiving opening in front of the machine between suitable frame extensions t8 and 49, to be hereinafter described.

I will now describe the means for feediiu.;` the plates one after the other from the bottom of the stack to the discharge point at the front of the machine. The feeding mechanism includes a pair of parallel reciprocating longitudinal bars 30 standing on edge and carrying pawls 85 pivoted to them and pressed upwardly to engage the plates. These bars are supported and guided near Ythe front in notches made through the transverse frame member 42,. andat their rear rest on flanged wheels 83 which are loosely journaled on a transverse shaft 100, hereinafter referred to.

Each of the pawls 85 is provided on its under side with a downwardly extending ear 86 which is Vnearly circular and connected with the pa-wl by a narrow neck, and occupies a correspondingly shaped recess formed in the upper edge of the bar 80.

The pawl is prevented from displacement by tvo collars 87 held to the sides of the pawl after it is placed on the bar by a through rivet pin 88. A detail of this pawl and its cooperating parts is shown in Fig. 16. The pawls are pressed upwardly by springs 89, seated in recesses in the upper edge oit' the bar and in the under face of the pawl respectively, limited by a tail 84 on the pawl, engaging the upper edge of the bar. rFliese pawls lie between the rails t0 and the frame webs 15 or "i6 and serve to engage the rear end of the tubular portion c of the address plate.

The reciprocatory bars 8O may be moved forwardly to feed the address plates by the following mechanism. rIhe two bars are connected by a yoke 90 pivoted to the bars at the rear end of the yoke. The forward end of the yoke is pivoted to the upper end of a second yoke 91, which at its lower end is pivoted to the frame members 15 and 16. The yoke 91 has a cross bar 93 which is normally engaged by a link 95 (shown disengaged in Fig. 11) the rear end of which is pivoted to a rock arm 96 pinned on the shaft 100, heretofore mentioned. On the outer end of this shaft is keyed a hand lever 102, carrying at its end a suitable handle 103. Then this handle is drawn forwardly and downwardly (assuming that the link 95 engages the rod 93), the feed bars are thereby moved forward, and on the return stroke of the operating lever the bars are return ed. A screw 99 carried by the frame member 4,1 serves to adjustably limit the rearward stroke of the feeding mechanism, and a spring 98 attached to the frame and to the rod 93 insures such return.

The feed bars are provided near their rear ends with upwardly extending portions 110 which rise to a sufficient height to come behind the bottommost plate in the stack. and when these bars are fed forward, the front edge 111 of these extensions engage the rear ends of the tubular portions a of the bottommost plate, and shove it out of the stack, while the top edges of the extensions support the rest of the plates in the stack. At the completion of the stroke, this advanced plate has been carried beneath the cover plate 9 to a point intermediate of the stack and the printing position, where it is adapted to be engaged by the rearmost pawl 85 on the next forward stroke.

It will be seen from the mechanism described that successive operations of the handle 103 may feed the plates one after the other forwardly from the stack to the intermediate position., then to the printing position and finally to the discharging position. In this operation. the plates travel over certain detent springs 120, which are secured to the rails l-O and have V-shaped noses entending upwardly through openings 121 in the the position being ["3 to make the impression.

rails 40. As shown, more particularly in Fig. 14, these V-shaped noses engage the successive grooves ,a3 in the underside of the address `plate and thus prevent their being jarred out of positionor carried too far by momentum `and also accurately'center them in the printing position.

The impression arm heretofore referred to, which'carries the platen6() is pivoted to brackets rising from the y bed. As shown, this impression arm is bifurcated and has two rearwardly extending arm portions 71 and 72 `formed to stand on opposite sides of the magazine. The portion 71 is journaled on a stud 78 carried by brackets 74 and 75, while the portion 72 is journaled to a stud 76 carried by a bracket 77. r'lhe arm 71 eX- tends beyond the pivot 7 3 in the form of an arm 78 which carries a roller 130. rl'his i' roller coacts with a cam 140 on 'the main shaft 100.

When the operating lever 102 is drawn forwardly, the cam swings the impression arm to carry the platen'60 downwardly The cam has a surface of increasing radius sufficient to carry the platen into impression action before the loperating arm has completed its stroke, and then the cam is purely concentric for the rest of its active surface, so that the slight rest of the platen while impressing is not accompanied by increased pressure. The roller 130 is maintained in snug engagement with `the cam at all timesby the spring anchored at its lower end to the frame and its upper end to an arm 146 integral with the arm 72. Suitable stops are provided for limiting the movement of the operating means shown in Figs. 5, 9 and 10 as comprising shoulders 147 and 148. and a stationary abutment 149 with regard to the frame.

It results from the above construction that whenever the operating arm 102 is drawn forwardly the amount of its stroke, the platen is brought down to a `definite point irrespective ofthe force applied to the operating arm. This causes uniform impression yto be given, notwithstanding variations in manual operation, and is an important feature of this invention.

To vary the depth of impression so that the same inking ribbon may readily ypr-oduce printing which is light, heavy .or mcdiuin, as desired. I adjust the position of "f3 the cam roller 130 in the arm K78. To elfect this, I mount this roller on an eccentric 131 and I provide suitable means for turning the eccentric and holding it in .adjusted position. As shown in Figs. 5 and 17, kthe eccentric carries an arm 134 which has an arcuate edge provided with worm teeth 135, and on the arm is suitably journaled a worm 136 meshing with these teeth and yhaving a knurled operating knob 137. By-Lthismeans, I can adjust to a nicety the impression beibamos? tween the platen and lplateand `retain the adjustment as long as-desired, 4the worm construction being self locking.

It isdesirable to provide `interchangeable platen surfaces of varying extent Cto enable eicient printing fromaddresses of different numbers of lines and to enablethe omission of the salutation where the addressplates carry the screws 155, the platen may be swungslightly for-ward, and by the reverse operai tion swung slightly rearward, and these screws also furnish means `for tipping the platen laterally to cause the underface of the ,platen to be strictly horizontal ywhen it is in impressingengagement.

The platen member 60 is shown as a hollow box-like member of U-shaped section having web portions and 161 keyed on a. rod 163, which is journaled lin `the depending portions 157 of the stirrup 151. The platen lisheld normally in theposit-ion shown in Figs. 2and 11, by reason of a squared portion on the web 161 engaging a rib 158 on the stirrup. `spring 166 surrounding the shaft 163 .and compressed between the web 161 andthe stirrup 157, normally lnaintains :the platen in this position. If, however, it `be shoved `to the right vin Fig. 7 a rounded portion l167 of the web 161 comes underthe rib 158 and then the platen may be turned in eitherdirection 90., to bring either of its other faces, into position `for action. A suitable knob 17 0 on the shaft 163 -furnishes means for vshoving Ait endwise and turning it. The endwise movement is limited by `the hub of the `knob engaging the stirrup 157, and rotation in this position is limited by lugs 171 on a hub engaging one side or the other ofthe rib 159 on the stirrup.

By having the kpads on the opposite sides of the platensurface of `less transverse extent than the normal `pad (as indicated at 168 and 169 in Fig. 11), I may readily eliminate the salutation, which may be carried by the address plate, or may eliminate if desired the address other vthan the name or such other material `as desirable, by simply turning the platen to one side or the other.

It is sometimes desirable to Aprint a date or other added matter which is not on the address plate. Toprovide for this, I make a suitable dovetail in the frame portion 173,

lof

Figfl, and I slide into this a holder 176, Fig. 19, which may have undercut projections 176 adapted to carry one or more printing strips 177. Such device stands at the side of the plate in printing position and lies beneath the inking ribbon, and the paper is impressed against it by a pad 17 8 on the entendA ed portion of the platen,v which houses the spring 166 heretofore mentioned. rlhe member 17 6 which carries this permanent printing surface may conveniently be curled over at its edge as shown at 179, Fig. 7, wnich forms a convenient sliding support for the ribbon and also provides ready means for drawingl out the spring holder.

l have referred to the inking ribbon 50 extending across the address plate which is above the frame member 42. riQhe arrangementof ribbon spools and the mechanism for mounting them, and for feeding the ribbon step by step succeeding each impression, and for reversing the direction of feed when a spool becomes empty is best shown in Figs. 6, 7, 8 and 18, and will now be described.

The ends of the ribbon are mounted on a pair of spools which are held one above the other, in the frame opening 17between the transverse web members .18 and 19. rlhese spools are clamped between two pairs of heads. each of which pairs is providecL with a ratchet adapted to enable the driving of Y that spool. More specifically, l mount in the web 19 a pair of stationary horizontal studs 181 and 180. On cach of these studs is a ratchet wheel 182 and 183, respectively, loose ly mounted on the stud. Connected with the ratchet wlieelsis a disk as 185, with a stud projecting through it and having a head beyond it. rlhe head of the stud is adapted to receive the opening of the ribbon spool with the disk 1,85 bearing against the flange of the sgool. r1"he spools are suitably locked to the ratchet wheel. disks 1.85 to eiiable their ready driving thereby, as for instance by pro# -iections 198 on the spool flange engaging openings 1911 in the ratchet disk as shown in Fig. 18.

Directly opposite the studs 180 and 181 are a pair of rods 186 and 187 mounted in the front of the frame and the cross web 18 and carrying disks 188 and projecting central portions beyond the disks. The spools are mounted between the front and rear disks and so maintained by springs 189 pressing` the rods 186, 187 rearwardly. These rods may be drawn to the front by knobs 190 and 191 to free the spools.

Vrlhen the spools are mounted between the disks as explained, the ribbon passes from the upper spool intermediately across the top of the bed over the adjacent portions of the top plates 8 and 9, and over the address plate which is in printing position (where the top plates are cut away) and then down the outer side of the exterior wall 1?. of the bed, which in this region is inset as shown at 195 to protect the ribbon, and thence passes under the frame of the machine and back to the lower spool. To guide the ribbon where it passes downwardly on the outside frame, I may mount within the inset portion 195 al plate 197 having at its edges vertical guiding projections 198, as shown in Figs. 2 and 6.

Due to the mounting described, both ribbon spools and the ribbon may be entirely removed from the machine whenever desired and no threading of the ribbon is necessary, which avoids any necessity for taking theribbon off the spools. r1`he simple act of pulling out the knobs 190 and 191 freesthe spools so that both the spools and the ribbon may be removed, and fresh pair Of spools and ribbon put in their place.

To feed the ribbon periodically during the operation, as well as to automatically reverse it when either spool becomes empty, 1 provide the following simple mechanism. Referring to Figs. 6 and 7, 200 designates a rod mounted in the frame portions 18 and 19. On this rod is journaled a bar 201 having a slotted end 202, in which is mounted a pin 203 carried by an arm link 204, the other end of which is pivoted at 205 to a rock arm 206 on a shaft 207, and also pivoted at 205 to a link 208 which carries a pin 209 adapted to engage the teeth of either ratchet wheel 182 or 183. A. tension spring 210 connects the pins 203 and 209. The shaft 207 carries at its other end a rock arm 212 carrying a roller 213 engaging the crown cam 214 on the main shaft 100. This cam is positioned to cause a movement of the arm 206 toward the right in Fig. 7, when the operating arm is drawn forwardly. This movement carries the pin 209 toward the right into engagement with a new tooth of the ratchet wheel, stretching the spring 210, then as the oper-l atino' arm is returned and the rock arm 206 swings in the opposite direction, ythe spring 210 retracts the pin 209, thus feeding the ratchet engaged by that pin and correspondingly turning the ribbon spool. rilhus following each impression, the ribbon is given a slight movement to present a fresh face for printing.

To cause the pin 209 to automatically shift from a full spool to an empty one, I mount on the arm 201, a roller 216 which is adapted to lie against the body of the ribbon wound upon the spool. As such wound portion increases in diameter, this roller gradually swings the arm 201 away from such spool and as the spool becomes filled, the arm has swung far enough to straighten the toggle provided by the two links 204 and 208, and then as more ribbon is wound on the toggle swings over into the opposite direction, as shown in dotted lines in Fig. 7, wherein the pin 209 engages the other ratchet wheel, as

llo

183, after Which the same movement ofthe operating lever feeds that wheel and the ribbon travels in the reverse direction. The slot 202 enables the movement of the links during the straight condition of the toggle.

To insure the mechanism described snapping guickly from one spool' to the other, I' provi 'e aI spring pressed' plunger 220mounted in a casing 221, rigidly secured' to the shaft 200. This plunger is pressed' outwardly by a spring 223. It has a V-shaped nose adaptedrto engage either of two sun faces on a Vishaped l'ugf225. on the bar 201'. Duringy the; gradual swinging of this bar 201, as the spool winds up, this lug camsthe plunger inwardly until' the point of the lug engages the point of the plunger, after which the reaction of the plunger tends to force the arm into position to cause engagement with the other ratchet.

llt is frequently desirable to set the inafor readily accomplishing this which I' will' now describe with particular references to Figs. 6 and 11.

Mounted inthe frame Webs 16 and' I7 1s a transverse shaft 230` on the outer end' of which is a ratchet Wheel? 231 having an even number ofteeth, preferably six, as shown in Fig. l0; Cooperating with this ratchet Wheel is a pawl 232- on` an arm 233 onthe shaft. This arm is connected by a link 234 with a rock arm 235, on they main shaft 100'. I also utilize this arm. 2351 for the attachment of the mainV springV 238A for returning the operating arm 102;

The mechanism described gives the ratchet Wheel 231 a fraction of a turn (e. g. l/G) for each operation of the machine. This ratchet wheel is pinned to the shaft 230 to Which is pinned a polygonal member 240 having half as many faces as the number of teeth on the wheel 231i. In this instance this member is a triangular block..

This block bears against an arm 241 which is pivoted onv a rod 242 which is tightly mounted in a pair of arms 248 journaled on the shaft 230.. The arm 241 extends rearwardly in the form of a rigid' extension 24:5 which has an upturned endf 24.6 adapted to engage the link. connected to the arm. 96 on the main shaft 100. A spring 2.47 tends to maintain this engagement. The rod 243 is. bent at right' angles and extends forvsf'ardly, as at 250, through at slot 251 in the frameand is provided with an operating knob 252. A pin 253 extends through the The mechanism described, givingy the shaft 230one sixth of' a turn for each operation, while the block *2&0 has only three sides, results in. turning'that block into the position shown in Fig.v 11, on every other stroke, while intermediately the point of the triangular block is engaging the arm 241 and thereby holding it down. The p0- sition, shown in Fig. l1 is the position, for duplicating and on the stroke represented in this figure, the extension 245 holds the arm 95A out of engagement with the rod 93 so that no feeding of the plates takes-place. On the next stroke, however, oneof the points` of the triangularv block-'240 engages the arm 2/1-1 and thus lowers the upturned" end 246 causing the link 95 to engage the rod 93, soy that on. that stroke the operation of the lever 102. feeds a plate. Accordingly the plates are fed with this setting for every other stroke. y

What may be called the normal setting ofthe machine-where the plate is to be fed for each impression-is Where the pin 253 of the setting rod is in engagement with the uppermost notch 258 of the latch 255.

ber 245 is lowered to such an extent that it cannot engage the link 95, Whatever thek position of the block 240. Accordingly the operation of the triangular block is entirely idle and the link 95 remains continuously connected with` the feeding linkage.

For a continuous printing from one plate, it 1s only necessary to lower the knob 252 to its lowermost position, Where the pin 2555 engages the notch 2,59; In this case the upturned end of the member 245y raises the link 95 so high that it cannot engage the rod 93 even When the triangular block 240 lowers the member 245. Accordingly the operation of that block is again idle and the plate feeding mechanism remains continuously disconnected from the operating shaft, enabling as'many prints as desired to be made from the' single plate. It will thus been seen that by this very simple mechanism, I am enabled to obtain normal operation, duplicating or the continuous printing from; one plate as desired.-

I will now describe the restacking ofthe plates after the imprints have been made. Fig. 11 shows: an address plate standing beneath the top plate 8 of the machine and in front of the address plate, which isreeeiving the impression.V On the next stroke this forward address plate is advanced 0E of the rails 4() over the open space between the this case the upturnedr end 246 of the mem? llo lli)

` stack lwas filled.

frame extensions 48 and49'; heretofore mentioned and drops by gravity. `When the manual transference of a few plates at a time to the storage drawer is intended, l place on the inner face of these frame parts 48 and 49 sheet metal liners 260 which have inwardly projecting flanges 51 at their lower edges. The delivered plates drop by gravity the lowermost plate resting on these flanges and Aeach surmounting plate resting on the plate below it. ln such ejection, the plate is prevented from being vcarried by momentum out of thisguideway by the upwardly extending frame flange 263 formed on the inner face of the frame portions 48 and 49.

"t/Vhen a reasonable number of plates have accumulated in the guideway the operator grasps them between his thumb and lingers extending through the open front of the machine and lifts them above the guideway and replaces tiem in a storage receptacle. To prevent jamming if the restaclrer magazine becomes entirely filled, incline the flanges 260 slightly toward the front of the machine, as shown in Fig. 11, with the result that the successive plates are similarly inclined so that when the stack is filled, the

topmost plate will lie at its front edge above the frame flanges 263 and thus the next plate delivered would simply shove this topniost plate out of the machine. No harm would be ydone and the operators attention would be called to the fact that the The machine described is complete in itself to effectively accomplish address printing. instead, however7 of placing compara'- tively few plates at a time in the receiving magazine and removing a like' number from the restacking device,y provide means, as already described, foi-:supporting an entire drawer of plates in place of the short sup# ply magazine. l also contemplate providing a sub-base for the machine which is equipped with means for horizontally stacking the delivered plates and is adapted to receive such drawer aftervits contents have been discharged into the supply magazine. The subbase is so arranged that the delivered and stacked plates will pass directly into the drawer upon its insertion in the sub-base, thus avoiding the necessity of removing a comparatively fewvat a time from the machine. I have made this sub-base entirely detachable from the main machine and still cooperating with it, so that it may be supplied either with themachine or supplied later to the users'who already have the ad'- dressing machine.

l will now describe thevsub-base with particular' reference to Figs. 1, 2, 3 and 5. The frame of the sub-base comprises a hollow casting having` walls which for the most part align with the walls of the addressingma#l ately, the side walls of the sub-base are braced by cross members 287 and 288. The front of the sub-base is open so that, after the platos have accumulated therein, the open ended drawer may be inserted horizontally into the sub-base and thus receive the stacked plates, after which the drawer may be withdrawn having plates within it.

W'ithin the opening in the front of the sub-base is rigidly secured an open frame 290. Extending rearwardly from this frame are two angle bars 291 which rest on the cross bars 287 and 285i. Resting on the horizontal flange of these angle bars are two flat strips 293, the rear ends of which are shown as curved around a stationary rod 294. EX- tending across the top of the sub-base is a horizontal bar 296 which carries an npwardly extending curved defiector 29"( adapted to extend between the frame eXtensions 48 and 49 of the adchessing machine. Now when a plate is delivered at the top of the space between these extensions it falls downwardly and by reason of the deflector assumes a vertical position and drops onto the forward end portion of the strips 293 between the vertical flanges of the angle bars 291, as shown at A in Fig. 2. f

in the position mentioned (Fig. 2) the address plate rests against an inclined gate 300. This gate is pivoted at its upper corner 301 to an open rocking packer frame which is pivoted at its lower edge by means of pins to the sub-base side members. The upper end of the rockingv frame 302 is connected by a pair of links 305 with a pair of arms 306 on the main shaft 100, the connection providing for loose play by means of slots 30T in the links. The portions of the arms 306 connected with the links are readily detachable from the portions connected with the rock shaft 100, enabling the ready separation when the sub-base is not employed. To effect this, I make the connection by flanges 308, the lower portion of the arm through which screws 309 pass into the up per portion of the arm. lllhen the sub-base is not used these upper portions are simply idle.

The operation of the packing mechanism described tips the foremost plate A which has inclined toward the front until it inclines toward the rear, where it rests against a suitable follower 310 or against the other plates already against the follower. This the strips 293 engaging slightly follower is supported on a :stationaryA bar 312 which is supported at its forward. end by the cross member 296 and at its rear end by being securedA to the rear wall 314 of the subbase frame. As the plates are discharged one after the other into theV sub-base the rocking packer causes the supply with the follower' to gradually travel backward so that eventually plates suflicient to fill an entire drawer may be accumulated in the sub-base.

As heretofore stated,the sub-base is adapted tohave the drawer shoved into it to receive the supply of plates. When. this 1 to take place the hinged gate 300 is swung upwardly on its pivot 301 as shown inA full lines in Fig.4 4 and .in` dotted lines in Fig. 2. Then the drawer is sho-ved rearwardly through the open member 290,the drawer being indicated at Bi in Fig. 4. '1"hisdrawer as'heretofcre stated has a bottom plate Z) and side walls b1 with turned-over top flanges b2. The. drawer also has plate retaining springs bt on its sides which have i inturned ends, which, when the drawer is idle, stand behind openings Zi4 in t-he side wall of the drawer'. Vhen the drawer is pushed into the sub-base, its botto1n plate passes under the supporting strips 293, the forward edge of whichis slightly beveled (Fig. 2) to lift it upon such insertion. The side wallsof the drawer pass outside of the ends of the plates which havebeen inserted, the plates being held centrally by reason of recessy bottom portionsof the plate, as shown in Fig.

5. As the dra-.Wer comes into its rearmost position, the int-urned ends of the springs b3 abut adjustable stops 320 carried by al cross web 322 of the sub-base frame, whereby those spring ends are brought into registration with the openings 7)* in the drawer walls and these ends then spring into the interior of the drawer through these openings and stand behindI the rearmost plate and alongside of the end ofr the follower' 310 which isnarrower than the width of the plate; At the same time a hole b5 in the bottom of the drawer comes beneath the nose of a gravity pawlf 325 (Fig. 2) carried by the follower andl this nose drops into the opening.

When the drawer is drawn out, the follower and plates-travel with it until the follower is brought back' to itsoriginal position when the nose of the pawl 325 rides up ony a spring 326l carried by the crossframe member 287 which frees the follower. Then the drawer is removed the rest of the way y with its load, the follower being left in starting position. Then the gate 300- is turned down into the position shown in full lines in Fig. 2 and the restacker is ready to receive another load of plates.

Before attaching the sub-base the lower ribbon spool is removed from its mounting,

and theribbon, instead ofL passing directly across the bottom of the main base, is then passed downwardly beneath the sub-base and beneath.y theV restacker and then the spool mounted in position, the course of the ribbon being indicated at 50 in Fig. 5. The subbase wall 230 has guides 33() for directing the ribbon whence it passes inwardly beneath the restacker, and as it turns diagonally upwardly it is guided by one of the angle bars 291.

It is frequently desirable to print addresses on a continuous strip of paper, as, for instance, when'y making a payroll list, instead of on individual cards. To provide for this, I furnish a simple listing attachlnent which is best shown in Figs. 3, 9 and 10, 12 and 13. This listing. attachment comprises a bracket 340 adapted to be secured to the side walls 13 of the main frame and carrying in suitable. bearings 341 and 342, a shaft 344. inner end, a knurled or other-wise surfaced feeding roller 345 adapted to engage the strip of paper. rllhe. outer portion ofthe shaft is connected by a suitable ratchet mechanism with the main operating shaft 100, whereby the roller may be automatically rotated, its lower surface traveling toward the rear, to feed the paper periodically. Coacting with the roller 345 is a spring plate 346 mounted beneath the roller and having its ends sprung into openings 347 in the top-plate 9 of the machine. The strip to be' printed, designated C in Fig. 12, lies between the spring plate and the listing roller 345.

I have provided a friction ratchet clutch, best illustrated in Figs. 12 and 13, in the connection between tlie operating shaft and the lister shaft 344. That is to say, pinned to the shaft 344 is a ratchet wheel 350 which is embraced by thebuilt-up hub 351 and 352 of an arm 353, and balls 354, pressed by springs 355, form the engaging means between the ratchet wheel and arm, as will be well understood. The arm 353 is connected by a link 2,57 with the rock arm 358 on the shaft 100, a slot 359 in the link providing loose play. Aspring 360 anchored toy the bracket 340 and to the arm 353 tends to turn the arm in the idle direction.

It results from the above described mechanism that as t-he main operating arm is drawn forwardly to effect an impression the spring 360 carries the ratchet armv 353 idly toward the front. Now as the operating arm returns the first port-ion of its movement docs not effect t-he lister roller 345 because the slot 359, but when the pin engages the right hand end of that slot (Fig. 13) the further movement rocks the arm 353 and through the ratchet connect-ion turns the roller 345. The amount ot this effective movement such as to feed the strip toward the rear Thisshaft has pinned to its I
